18 GHz 2000 V.DC Large-Diameter Low-PIM High-Power RF Cable B76

Engineering Note

The B76 is a high-power flexible RF coaxial cable positioned as the larger 2000 V.DC 18 GHz option. It keeps the confirmed B-series construction with LD PTFE dielectric, aluminum foil interlayer, silver-plated copper shielding, and blue FEP jacket, while emphasizing 7.62 mm blue FEP jacket for larger 2000 V.DC high-power routing. Use it for RF routes where the confirmed electrical class and cable size fit the system envelope.
